Abstract:

Samples for granulometry analyses on the Northeast Greenland shelf have been collected with R/V Polarstern during PS109 between September and October 2017 using a camera-equipped multiple corer (TV-MUC; core area 0.007 m²). Upon arrival on deck, the upper 5 cm of three MUC cores were sliced into 1 cm intervals, using a cut-off syringe in order to get a depth resolution of the grain size distribution, and stored in 20 ml scintillation vials or plastic bags. In the laboratory, the grain size spectra were then assessed by laser diffraction (Malvern Instruments, Malvern, UK).
